Filter dict to contain only certain keys?

Question

I\'ve got a dict that has a whole bunch of entries. I\'m only interested in a select few of them. Is there an easy way to prune all the other ones out?

Answer 1

Here is another simple method using del in one liner:

for key in e_keys: del your_dict[key]

e_keys is the list of the keys to be excluded. It will update your dict rather than giving you a new one.

If you want a new output dict, then make a copy of the dict before deleting:

new_dict = your_dict.copy()           #Making copy of dict

for key in e_keys: del new_dict[key]
